  • Catalogue Essay

    Patek Philippe’s perpetual calendar chronograph reference 2499 is often considered by collectors as the crowning jewel of a collection. Each time a model appears, the auction room is filled with a sense of exhilaration. However, when a model is unknown like the present watch and appears on the market, exhilaration turns into euphoria.

    Reference 2499 is the proud heir to reference 1518, the very first perpetual calendar chronograph wristwatch made in series in the history of horology. It replaced reference 1518 in 1951 and was made for a period of 34 years until 1985. The reference was produced in four different series.

    With the fourth series, Patek Philippe added /100 to the reference number which consequently became ref 2499/100. Considered the last true vintage Patek Philippe chronograph wristwatch, the present reference 2499/100 has an exceedingly unusual feature of having a sapphire display back.

    It was only in the late 1980s that brands started offering sapphire crystal backs on their timepieces. Before that, sapphire backs were reserved for deck watches and chronometers submitted to timing trials.

    Legend has it that a prominent European collector, wishing to be able to admire the superb hand finished movement of his reference 2499/100, contacted Patek Philippe in the early 1980s to obtain a sapphire crystal back for his timepiece. Obviously, the case back could not be simply cut open to have a crystal inserted. Therefore, Patek Philippe created a new caseback for the watch, similar in shape to the bezel and crystal. Since the gold hallmarks, case maker's mark, reference and case numbers could not be stamped in, or outside of the caseback, Patek Philippe decided to stamp all gold and case maker hallmarks beneath the lugs. The case and reference numbers were inscribed within the case, which we also see on the present example.

    Until today, only 3 reference 2499/100s with a display case back were known: one belonged to the collector having ordered the first watch, one was made for Mr. Philippe Stern and another was made for a Patek Philippe director. We are delighted to have discovered the present fourth model, previously unknown and fresh to the market which will certainly be the crown jewel of any collection.
